On list is a dual rail regulator PCB to be used with low current application ( below 300mA). using LM317, LM337. This board is particular useful for preamplifier or headphone amplifier. The broad includes protection circuit to protect the regulator chips from high output voltage reversal.
This board need an AC voltage 12Vx2 to 15Vx2 ( for +/-12V DC application).
PCB Dimension : 60mm x 96mm
PCB copper thickness : 75um ( 4 times standard thickness !)
